This is a stupid newbie question!

I have 2 arraylists which are linked. One arraylist contains values 1-30 and the other contains a short "memo".

how do i go about displaying all of them in the terminal window so that when a number is selected from arraylist 1 the corresponding value is selected from arraylist2.

Can i sort arraylist1 into ascending order so that when the values are displayedit would be like...1, 2, ...

Thank you for your time
